SINGLE OUTPUT CHANNEL LOW NOISE AMPLIFY APPARATUS FOR RECEIVING MULTI-MODE MONO PULSE SIGNAL AND OUTPUT METHOD THEREOF

摘要

The present invention provides a single output channel low noise amplification apparatus for receiving a multi-mode monopulse signal and an output method thereof. To this end, when a basic mode signal and a higher-order mode signal are inputted from the antenna device, the basic mode signal and the higher-order mode signal are low-noise amplified. The amplified high-order mode signal is frequency-converted, and the amplified fundamental mode signal is combined with the converted high-order mode signal and outputted to the splicing device through one output channel. Then, the splicing device transmits the combined signal through one transmission channel, and the transmitted combined signal is separated and processed into a fundamental mode signal and a higher-order mode signal according to the frequency by the signal separator. Accordingly, since the output channel of the low noise amplifying device is unified, the present invention can simplify the structure of the rotary joint and the pedestal device including the rotary joint. Therefore, there is an effect that the OTM satellite terminal can be further reduced in size and weight.
